Detailed Description

DtLightSignalSequenceGenerator generates a sequence of on/off times like the S57 SIGSEQ attribute based on the LITCHR, SIGPER, and SIGGRP atributes.

While the S57 SIGSEQ attribute provides the most accuracy as to how a navigation light operates, it is an optional parameter and not always included. An instance of this class can be used to approximate the light sequence to the point where the light's sequence properties should be recognizable.

Geerate a signal sequence based on the S-57 light characteristic, period, and signal group parameters.

A signal sequence is a vector of floats which represent light on and off times, respectively

void makVrv::DtLightSignalSequenceGenerator::generateMorseCodeSignalSequencesMap

(

)

Called by the constructor to initialize a map of Morse Code sequences one for each letter and digit.

This needs to be called again if any of the Morse code-related defaults are changed

virtual void makVrv::DtLightSignalSequenceGenerator::setDefaultAlternatingPeriod ( float  defaultPeriod )

virtual

Set defaults used for generating signal sequences.

The default periods are technically not necessary, since this is a required attribute for all non-fixed lights. The are included for completeness in the case(s) where data may be incomplete. Set the default period for alternating lights Initialized to 4s

virtual void makVrv::DtLightSignalSequenceGenerator::setDefaultFlashPeriod ( float  defaultPeriod )

virtual

Set the default period for flashing lights Initialized to 2s.

virtual void makVrv::DtLightSignalSequenceGenerator::setDefaultLongFlashPeriod ( float  defaultPeriod )

virtual

Set the default period for long lights Initialized to 10s.

virtual void makVrv::DtLightSignalSequenceGenerator::setDefaultQuickFlashPeriod ( float  defaultPeriod )

virtual

Set the default period for quick flashing lights Initialized to 1s.

virtual void makVrv::DtLightSignalSequenceGenerator::setDefaultVeryQuickFlashPeriod ( float  defaultPeriod )

virtual

Set the default period for very quick flashing lights Initialized to 0.4s.

virtual void makVrv::DtLightSignalSequenceGenerator::setDefaultUltraQuickFlashPeriod ( float  defaultPeriod )

virtual

Set the default period for ultra quick flashing lights Initialized to 0.2s.

virtual void makVrv::DtLightSignalSequenceGenerator::setMinimumFlashOnTime ( float  defaultTime )

virtual

Set the minimum on-time for all flashing lights.

The on-time for an ungrouped light is typically 10% of the period, but not less than this minimum. The minimum is not used for very quick or ultra quick flashing lights, since their periods require a smaller on-time. These two faster flash types are typically isophased (and grouped). Initialized to 0.3 seconds

virtual void makVrv::DtLightSignalSequenceGenerator::setMinimumLongFlashOnTime ( float  defaultTime )

virtual

Set the minimum on-time for a long flashing light.

Initialized to 2s

virtual void makVrv::DtLightSignalSequenceGenerator::setDefaultMorseCodeDot ( float  defaultTime )

virtual

Set default values used for generating Morse code signal sequences The international Morse code standards states: short mark (·) — "dot duration" is one time unit long longer mark (–) — three time units long inter-element gap between the dots and dashes within a character — one dot duration or one unit long short gap (between letters) — three time units long The defaults used do NOT conform strictly to these rules, but follow the example sequences found on all Morse-code signalling buoys in Boston and Honolulu harbors.

If you change them, call generateMorseCodeSignalSequencesMap() to regenerate the character map. Set the default on-time for a Morse code 'dot' Initialized to 0.4s

virtual void makVrv::DtLightSignalSequenceGenerator::setDefaultMorseCodeDash ( float  defaultTime )

virtual

Set the default on-time for a Morse code 'dash' Initialized to 2.0s.

virtual

Set the default Morse code inter-letter gap.

Initialized to 2.0s

virtual void makVrv::DtLightSignalSequenceGenerator::setDefaultMorseCodeGroupSpacing ( float  defaultTime )

virtual

Initialized to 9.0s

Morse Code.

• returns morse coded sequence(s) for the specified letter(s) and/or digit(s)returned by morseCodeSequence() followed by the remainder of time from the specified period. Example. Given a Period of 16.s and a SIGGRP of (AA) - morseCodeSequence('A') returns [myDefaultMorseCodeDot] [myDefaultMorseCodeDotDashSpacing] [myDefaultMorseCodeDash]. To add the second 'A', we need a letter spacing: [myDefaultMorseCodeLetterSpacing] and then repeat the 'A' sequence: [myDefaultMorseCodeDot] [myDefaultMorseCodeDotDashSpacing] [myDefaultMorseCodeDash]. The method then adds up all the time used by the sequence 'AA'. Using the default timings, that would be 0.4+0.6+2.0+2.0+0.4+0.6+2.0 = 8.0. So a final offtime of 16.-8.=8. seconds ends the sequence.
